✔ 最佳答案
-13 + (+12) - (-5/8)
= -13 + 12 + 5/8
= 12 - 13 + 5/8
= -1 + 5/8
= -8/8 + 5/8
= (5-8)/8
= -3/8
-13 + (+12) - (-5/8)
= -13 + 12 + 5/8
= 12 - 13 + 5/8
= -1 + 5/8
= -8/8 + 5/8
= (5-8)/8
= -3/8
參考: me
-13 + (+12) - (-5/8)
= -13 + 12 + 5/8
= 12 - 13 + 5/8
= -1 + 5/8
= -8/8 + 5/8
= (5-8)/8
= -3/8
答案是負8分之3。
(-13)+12-(-5/8)
=(-1)+(5/8)
=(3/8)
所以答案是3/8(八分之三)。

對不起,答案有錯誤!(-13)+12-(-5/8)=(-1)+(5/8)=(-3/8)所以答案是-3/8(負八分之三)才對。
5
(-13)+(+12)-(- - )
8
5
= -13+12+ -----
8
3
= - ----- or - 0.375
8
參考: me
( - 13 ) + ( + 12 ) - ( - 5/8 )
= - 13 + 12 + ( 5/8 )
= - 1 + ( 5/8 )
= ( - 1 * 8 + 5 ) / 8
= ( - 8 + 5 ) / 8
= - 3 / 8
= -13+12+5/8
= -1+5/8
= -8/8+5/8
= -3/8
參考: me
-13 + (+12) - (-5/8)
= -13 + 12 + 5/8
= 12 - 13 + 5/8
= -1 + 5/8
= -8/8 + 5/8
= (5-8)/8
= -3/8
